Reproduction of plants by asexual means, i.e. without seeds. In this process, different parts of a plant (shoots, root parts or, as with many flowers, bulbs) are planted in the ground, from which roots and shoots can then develop. In nature, sexual or generative reproduction usually takes place, i.e. the product is genetically different from the parents, which usually produces offspring that are strong enough to survive. However, there are also some plants with natural vegetative reproduction (e.g. various moss species). Vegetative propagation is used in plant breeding to produce plants in large quantities. In viticulture, this is understood to mean propagation by mostly planting blind vines of a mother vine. Since the grapevine is extremely heterozygous (cleaved), propagation, i.e. the production of grapevines in nurseries, is principally carried out in a vegetative way.
